hello everyone, could someone help me with this hameg hm5006 spectrum analyzer? basically this instrument fell and did not turn on anymore, I disassembled the power supply and replaced the tda4506 and after many attempts it turns on and works for a couple of hours. I turn it off and on again and I hear a bang, I disassemble the power supply board and find acid on it, so I replace all the capacitors but nothing, it turns on late and the screen does not work anymore. I attach the manual. thanks in au. |

Hi! Have you checked the voltages acoording to service manual? Please be careful there is 2 kV present here! Could you make a good photos of PS. |

hi, thanks for the reply. i checked the voltages and they are 0v when it does the fault. after several attempts to put and remove the plug it turned on, i measure the voltages and they are all ok as the manual says. the cathode ray tube does not turn on anymore while all the other things work. |

Check the voltage on pin 6 TDA4605 when PS does fault. It must be above 12(13max) VDC to turn PS on. Also check voltages on C1017 and pin 3 TDA4605. |

PIN 6 11,8v don't work, 12,4v work PIN 3 0,5v don't work Tomorrow view other measure |
